IMPROVEMENT IN ROTARY ENGINES.

specification forming part of Letten; Patent No. 173.744, dated February 22,1876; appiieatiommed Y July 22, 1875.

To all whom it may concern:

The nature of my invention consists in the construction and arrangement of a rotary engine, as will be hereinafter more fully set fortli. In order to enable others skilled in the art to which my invention appertains to make anduse the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in .which- Figure l is a longitudinal section of my ro, tary engine. fFig. 2 is a transverse section of the same through the center of the wheel.

A representsthe casing of my rotary engine, constructed to receive the center Wheel B and the two side wheels C C. The center Wheel B is vformed or provided with four lugs,

f a a, on its periphery, at equal distances apart,

to lit in corresponding recesses b b on the These parts are all constructed in the same manner as inV other engines of this class.

Thecasing A is, at each end, formed with a pocket, D, which becomes filled with steam, carried into it by the recesses b in the wheels C C. The steam in the pockets D D serves to balance the wheels C C by exerting a counter -pressure at a point opposite the point where the steam-strikes the face of the wheel.

The center wheel B is formed with an annular recess on one side, which lits snugly over an annular steam-chest, G, secured to the head of the casing. This steam-chest is, in its periphery, provided with two elongated ports, an av, opposite each other, and in the wheel B, behind leach lug a, is a steamport, y, for the admission of steam. The steam enters the steanrchest throughy an aperture, y, in Fig. 2.

The length of time the steam acts direct is regulated by the length ot' the port ai.

When the ports have passed so that there is no communication between the steam chest .y

and cylinder,the steam works on expansion until the next port, y, comes around to the port w.

I do not broadly claim a cylinder of a rotary engine constructed to form a steam-space around a portion of the periphery of the revolvingabutment, whereby the latter is nearly balanced by the pressure of steam, as such is notmy invention. i

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

In a rotary engine having the casing A and wheels B and C C, the pockets D D, formed in the ends of the casing, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 1st day of July, 1875.
